BACKGROUND
As the international birthrate is decreasing and the aging population is increasing, rejuvenation in older adults is required, especially in developed countries. Therefore, older people must act as active social participants to improve their health. With a recent spread of information and communication technology (ICT), older people can use ICT to improve their health and interact with others, and ICT can promote the social participation of older people. However, owing to its design issues, ICT use is limited among older people. Therefore, it is necessary to develop ICT that is suited to the needs of older people. We developed a communication application, “kikoeru,” based on the needs of older people and verified its physical and social effects. The functions of the app include conversations with voice messages, sharing of photographs, and sharing a pedometer among users.
OBJECTIVE
This study aimed to clarify the effects of connection, subjective health, loneliness, and motivation to walk using kikoeru.
METHODS
The subjects were seven men aged 65 years or older who did not receive outpatient treatment for dementia in the community. The study design was a controlled before-and-after trial. The effect of kikoeru was measured using a mix of quantitative and qualitative methods by means of a questionnaire and oral interviews. The survey items consisted of the Ando-Osada-Kodama (AOK) loneliness scale, target steps completed, and a rating of subjective health. In the interview, we asked "Did you feel connected when using the app?" In addition, the usage days of the app were collected from the server.
RESULTS
Participants used the app for an average of 54.9 days during the 60-day intervention period. The running days when they did not use the app averaged 1.9 days. As a result of the interview, use of the communication app created the following four connections: “Reliance construction,” “Remembering to consider friends ,” “Cognition of friends’ daily life and using it in my life,” and “Taking an interest in friends.”Loneliness improved for four out of seven people, was maintained by three people, and did not get worse for anyone. The target number of steps improved for three out of seven people, was maintained by four people, and did not get worse for anyone. The subjective health feeling improved with a perfect score of 100. The score rose from 63.6 points to 72.9 points after the intervention.
CONCLUSIONS
Older people experienced a reduction in loneliness after creating connections with their older friends using the functions of ICT communication tools. A competitive spirit that developed through communication using ICT among older males might improve their target number of daily steps and subjective health.
